I am looking for 3.3V-compatible (for the control signals) character displays, preferably fairly large, lots of chars (say 4x40)

1. I found a device, NHD-0440AZ-FL-GBW, on digikey.com but for some reason it seems not to be available on this website.(Here, the NHD-0440AZ-FL-YBW is available, but its inputs need to be 5V) Why is that device not available here?
